I'm having a problem with the following command:

fastq-dump --split-files --origfmt SRR1611183

Here is the error message:

2018-03-06T01:50:18 fastq-dump.2.3.5 err: error unexpected while resolving tree within virtual file system module - failed 

to resolve accession 'SRR1611183' - Obsolete software. See ( 406 )

2018-03-06T01:50:18 fastq-dump.2.3.5 err: item not found while constructing within virtual database module - the path 'SRR1611183' cannot be opened as database or table

I've researched the issue on the web and the consensus was that I needed to update my sra toolkit to the latest version 2.9.0 (so I did); however, I'm still getting the same error message?

Some more troubleshooting, I type in the following:

$ which fastq-dump

and get...


Then I try a test from the github instructions:

fastq-dump --stdout SRR390728 | head -n 8

and get the same error...


I guess I could just download the data directly from EMBL-EBI ( but I really want to figure this one out.

I am not sure what happened to my previous but it seems to have disappeared.

I was able to replicate the error using an older version of the fastq-dump (2.5.2), however, newer version of the fastq-dump (v2.9.0) works just fine.

Works for me using v.2.8.2.

Thanks - I don't understand why I'm all the sudden having issues. I was able to run this command with no problems last month?

Have you tried re-running vdb-config utility to set paths for temp directory (and any other options)?

I looked in to the feature but my directory should be ok, I have 80 GB of free space and only need ~ 15GB. I'll try again and report back.

edit - I ended up removing and purging the entire sra toolkit and then re-installing from scratch, starting with the wget function.

I'm happy to report that it seems to have done the trick!
